Yugi: You can't fix all your problems by mind-crushing people!
Yami Yugi: Oh, come on! Just one little mind-crush, it'll barely hurt him.
Yugi: No! Bad pharaoh! No mind-crush!
The Kid with the Remote Control, but with a twist: the controlled partner or servant is pragmatic at best, and a raving loon at worst. The loyalty of the servant varies, but the typical example is essentially a portable version of Sealed Evil in a Can — though a very loyal one can be even creepier. The servant openly admits his opinion that the best way to deal with obstacles and enemies is through complete annihilation. The kid (who is usually younger) is the moral compass who has to keep it under control (with a little help from the Restraining Bolt), and more importantly not fall victim to temptation.
Naturally this works both ways, where the monster learns empathy and grudgingly accepts his master might not be so bad, while the handler learns not all things are as black and white as they think.
This is one of two things that can result from trying to control Sealed Evil in a Can. For the other, more cynical outcome, see Evil Is Not a Toy. Compare Guardian Entity and Morality Chain, when the restraining is more emotional.
- The title characters of Ushio and Tora. Ushio's the kid who keeps the demon Tora at heel with a magic spear, as the two begrudgingly cooperate in fighting demons.
- InuYasha, initially; in early episodes Kagome made Inu-Yasha behave himself with the help of a magic necklace that slammed him to the ground when she said the command word (osuwari, or "Sit"). She never actually stops doing this, but in later episodes it's usually provoked more by romantic-comedy wackiness than actually restraining him from violence... except in regards to his Super-Powered Evil Side.
- Hellsing: After her father's death, Integra Hellsing likely spent the rest of her childhood holding the leash of the ravenous vampire Alucard — which could well explain a lot about her personality. Something uncommon about this example is that Alucard's loyalty is real. He truly likes to serve Integra, he even respected her ancestor (Abraham van Helsing, the man who defeated and sealed him) having thought of him as a Worthy Opponent.
- Mahou Sensei Negima!:
- Evangeline's first partner, the doll Chachazero, is a bloodthirsty thing that would rock Chucky's boxers. She often councils her mistress towards violence, murder, and mayhem. This is despite the fact that Evangeline herself is already a notoriously evil vampire sorceress with a huge bounty on her head...
- Also inverted in Evangeline's relationship with her other partner Chachamaru, a gentle-souled Friend to All Living Things of a Robot Girl.
- Komachi and her "sidekick" Kikuchiyo in Samurai 7.
- Shin'ichi Izumi from the manga Parasyte / Kiseijuu exists in an uneasy partnership with "Migi", the parasitic alien that took over his right hand while attempting to eat his head.
- In a way, the title character of Naruto embodies this trope, as did Gaara before the events of Part 2. Naruto's "partner" is concerned mainly with protecting himself and therefore Naruto, and only aids him if he is in danger. Besides keeping itself alive, the fox has an ulterior motive to letting Naruto draw on its power: once enough tails are released it starts to regain physical form. And the more often Naruto draws on its power, the easier it becomes for the Kyuubi to influence him. As of chapter 570, Kurama (the fox) is now very willing to help Naruto out, having grown to deeply care for him and possibly believing him to be the reincarnation of the tailed beasts' father figure, The Sage of the Six Paths.
- In the recent chapters of Claymore, it's shown that Raki has essentially become the leash-holder for Priscilla, who's taken on a much smaller form since she apparently hasn't been eating people lately and has been helping Raki find Yoma. Priscilla, by the way, is more or less the strongest awakened being ever. Raki, however, admits that he may have to kill her at some point, and that she likely will eat him first if he tries.
- In a mild version of this trope, Kaname Chidori from Full Metal Panic!! inspires a great deal of loyalty and protectiveness from her bodyguard Sōsuke, who is both capable of and willing to unleash copious amounts of carnage to keep her safe (much to her chagrin). The pair's relationship is at one point described as that of "a rabid dog and its master".
- Yugi is an arguable example, once he figures out how to communicate with the 3000-year-old pharaoh possessing his necklace, and tells him that ideas of justice have changed somewhat in the last couple of millennia.
- While the Pharaoh/Yami Yugi stops mind-crushing people in shadow duels after the Duelist Kingdom arc and becomes much more merciful and reasonable out of his own free will, sometimes he still needs the leash — for example, when he wins in a duel that Pandora jury-rigged so that the loser will have his legs cut off by circular saws, and Pandora starts screaming and begging in terror as the saws approach him, Yami folds his arms and doesn't make a move to help him, incensed that Pandora tried to kill him and Yugi. Yugi has to forcibly take back his body in order to rescue Pandora. Additionally, in season 4, when an enraged Yami breaks the leash and blocks Yugi from his mind and body to stop him from interfering in his attempt to punish Rafael for claiming he was a bloodthirsty tyrant when he was a king, the results are predictably disastrous.
- Subverted (and sometimes subverted again) in Chrono Crusade. Considering Rosette is in a contract with a demon, it seems like they'd have this sort of relationship, and Rosette's commander, Sister Kate, is openly suspicious of her partner. But Chrono himself is a kind-hearted person that, in the words of another character, "wishes not to harm anyone." However, he does have a Berserk Button that sets off his demonic instincts at times—meaning that occasionally Rosette does have to step in and order him to stop.
- Nora: Magari Kazuma is a rare example of a Kid with the Leash who really isn't shy about yanking it; both he and the Dark Liege view his contract with Nora entirely through the lens of "obedience training" (not that you can really blame them).
- Tsuna and Gokudera from Katekyō Hitman Reborn! have a relationship rather like this. Gokudera seems rather eager to kill people he dislikes (which include pretty much everyone except Tsuna), with Tsuna constantly having to restrain him. His love for his boss is pretty much what keeps him from killing / beating up most people.
- Ciel from Black Butler is a 12 year old rich kid in control of a demon who just happens to be working as a butler in his mansion. Sebastian, the demon, pretty much does whatever Ciel tells him to do. He won't do anything without Ciel ordering him to.
- In Cyborg 009, we have a boy (0013) and a Mysterious Waif (Princess Ishuki) as the controllers of two enormous, murderous robots. Neither case goes well.
- Naeka's hold over her 'servant' Kogarashi in Kamen no Maid Guy, who will use his wacky superpowers in increasingly outlandish and sociopathic ways to 'help' her. Said hold was tenuous at best even before the Restraining Bolt broke in the second episode and the only way to restrain him after that is with the good old Ultra-Violence.
- In an omake story, Tom's relationship with Shizuo is shown to actually be a subversion. Tom is actually insulted by suggestions that Shizuo is his to control ("The kid isn't a dog.") and, despite the fact that Shizuo was hired to be Tom's bodyguard, Tom actively avoids making Shizuo fight for him. In fact, several details (such as who pays for Shizuo's property damage) imply that Tom offered the job mostly for Shizuo's benefit.
- There is however, a straight example with Anri and Saika. Saika basically spends all of its time in Anri's head incessantly suggesting that she should let it "love" anyone and everyone, especially Shizuo. Anri is understandably a little distressed by this.
- Yukki fills this role in Future Diary. He is the only one that can stop Yuno whenever she tries to kill people. Considering they are in a life or death survival game, he has to let her loose more often than most.
- While Alice likes to pretend otherwise, it ultimately IS Oz who holds the leash in Pandora Hearts. The terms of the contract between the teenage nobleman and the demonic, scythe-wielding 'Bloodstained Black Rabbit' are uncertain at best, but Oz's superb willpower means that he can effectively shut down Alice if she gets out of hand. Or the fact that those powers were his to begin with, and Alice was just a vessel for said powers.
- Bastard!!'s Dark Schneider was all about this. A virgin maiden's kiss and a spell released him from his childish body and transformed him onto the cruel, evil and horny black mage.
- The Loveless manga seems to be headed this way, with Ritsuka holding Soubi's leash when he wants to "deal with" Ritsuka's mother in violent (and permanent) fashion. Lately, he's also started down the "teaching morality" track.
- Virgin Ripper: Nagi is a kitten who becomes a cat-boy shinigami (think Schrodinger with Captain Kuro's sword gloves). After being traumatized he thinks the title "Ripper"note is his mama and will do anything to protect her, including "making squishy" anyone who threatens her, even her friends. She will no doubt try to correct this but trauma or not Nagi is still a cat.
- In Kamisama Kiss an ordinary teenage girl, Nanami Momozono, is made the new Land God of the Mikage shrine and ends up with Tomoe, a powerful and ruthless demon, as a familiar. He is none too pleased about having to serve Nanami at least initially but thanks to the familiar contract is forced to obey any order she gives him.
- Gangsta.: Worick is the "kid" holding Nicolas' leash, and that's only due to the deep relationship and respect between the two. Though hardly a saint himself Worick has been responsible for preventing Nicolas from attacking or killing unnecessary targets more than a few times.
- The pot of Ayakashi Koi Emaki has the priestess Miko as the kid with the leash of the youkai Kagura, whom she sealed into a Sleep-Mode Size.
- Blue Beetle: Jaime Reyes with the scarab. Much of the dialogue between the two consist of Jaime rejecting its suggestions to kill somebody. According to Metron, it shouldn't even have a "non-lethal setting."
- The DC-Verse being pegged way on the sunny end of the Sliding Scale of Idealism vs. Cynicism, though, the scarab eventually comes around completely to its partner's way of thinking.
- Early on in the 2011 reboot things took a downward turn. The scarab is an Ax-Crazy killing machine that barely responds at all to Jaime's wishes. Jaime had to flee his hometown to prevent the Scarab from killing everyone around him. This is still a better deal for Jaime, since the Scarab normally should have taken full control of him. Jaime has recently gained much more control, though the Scarab's Plan A is always to kill.
- Takato fulfills this role towards Chaos in the Tamers Forever Series
- In All You Need Is Love Naomi feels like this. She knows Light is a psycho but he could be so much worse... Also Naomi with her son Duck. "No starting religions!"
- In the AU Green Glass: when four year old Harry Potter receives Tom Riddle's diary...
Tom: There are all sorts of spells; hexes and jinxes, curses, charms... there are spells to find things, to protect you, to hide things, and spells to hurt the people who hurt you.
Harry: Like Abra Kadabra?
Tom: Yes. Like Abra Kadabra.
- From The Jaded Eyes Series:
- Death Note: The Abridged Series (kpts4tv):
L: Bad Light! No killing!
- Taylor is this towards the Endbringers in With Friends Like These.
- In Sol Invictus, Zoro would only take orders from Luffy. The other characters note that she seems to be the only one who can do it.
- In Terminator 2: Judgment Day, John Connor discovers early on in the film that he has complete verbal control over the Terminator cyborg played by Schwarzenegger. Of course, he also learns he has to word his instructions carefully — an instruction to not kill anyone leads to a guard getting shot in the leg, with the explanation, "He'll live."
- The premise of Danny the Dog (known as Unleashed in some countries) is a variation in which a gangster has raised a man as a dog — a dog with deadly martial arts skills — who, when he has his collar removed, serves his master's whims rather than his own, mainly debt collection and pit fighting. Guess what happens...
- In Dragon Bones, the Affably Evil villain has a servant who is very sadistic, and has to be held back in order to achieve his long-term villainous goals. He also has a big, scary monster, that is held under control by several wizards.
- Good Omens: To signify The End of the World as We Know It, the Antichrist is sent a fearsome and terrifying hell hound that is his to command. However, as the Antichrist has grown up as an ordinary boy who is completely unaware of his destiny, upon its arrival he unwittingly commands it to become an ordinary pet dog — and as the novel progresses, the hound becomes progressively less interested in tearing the throats out of the innocent and more interested in chasing cats.
- Deconstructed/subverted in The Bartimaeus Trilogy: Nathaniel (an apprentice magician) firmly believes that demons are Always Chaotic Evil, and that elaborate incantations and careful wording are necessary to keep enslaved summons in check. While this is not entirely unjustified (Bartimaeus is very open about his willingness to free himself by killing Nathaniel if he had the chance), Bartimaeus — the demon — is often more moral than Nathaniel. He complains about being given less-than-ethical tasks, and there are hints throughout the series that both the djinni and the boy would be better off if Nathaniel relaxed the restraints and simply trusted him.
- The rule is kept, however, with Bartimeaus' favorite master, Ptolemy, who was able to form a strong bond of trust through his companionship until his death. He is the one who originally formed Bartimaeus' ethics.
- Mogget in the Old Kingdom trilogy by Garth Nix. He's an incredibly powerful and very, very angry Free Magic creature, but a powerful Charter Magic spell in his collar locks him into serving the Abhorsens and cuts off a lot of his power. If the Abhorsen takes off his collar, he returns to his original form and helps them for a little bit. Unfortunately, he then starts on a Roaring Rampage of Revenge against the people who've been controlling him for centuries. (Although it's not a matter of him having something against the Abhorsens personally; it's just that he really wants to get back at the Seven for binding him in the first place, and guess who happens to embody the remnants of Saraneth?)
- There's an odd example in the Discworld series with Death and his servant Albert, with Death being the "kid" and Albert the one on the leash. In life, Albert was a malevolent wizard and, when he knew he was going to die, performed - in reverse - a ritual that was supposed to summon Death, on the logic that it would send Death away from him. Instead, it sent him to Death. Albert has "lived" for centuries in Death's Domain and can now only spend a limited time on earth before his remaining minutes of life are used up. While Albert is not a physical threat to Death, he is much more cynical than his master, and in several books evidences a willingness to betray his master and regain his status in life.
- It helps that Albert is heavily implied to be vastly more powerful than his wizened, chain-smoking form would lead you to believe. Albert and Death are fond of one another in an odd way though.
- Possibly the most extreme leash is from Terry Pratchett's Small Gods where Brutha — the humble servant — holds Om's — the omnipotent deity — leash as the last person who believes in him. Since a god's power and very existence is based on belief, Om has to follow Brutha and keep him interested in worshipping him. Even once he manages to win back more followers than ever, he's still loyal to Brutha's commands.
- And of course, Rincewind theoretically has this relationship with The Luggage, occasionally trying to stop it from completely slaughtering everything in the vicinity.
- Heroine of several Forgotten Realms short stories (Thieves' Reward, Thieves' Honor, Thieves' Justice) by Mary H. Herbert, thief Teza managed to
swindle Anti-Villain out ofmagically bind an aughisky - a very rare sentient humanoid-eating horse. She both rode him and got rid of many enemies by her monster's teeth. Teza loved even normal horses and cared very well for the most cool and beautiful mount she ever saw. That paid off when control was broken: instead of simply devouring her, the aughisky saved her life and left. And even allied with her later on.
- A mild version in the Honor Harrington series. Sphinxian Treecats believe that there are only two kinds of enemies: Those who are dead, and those who are not yet dealt with. This is due to a combination of the unforgiving deadliness of many predators on Sphinx (including the Treecats themselves), and the fact that the Treecat trait of Telepathy means that there's no point to being subversive or subtle in Treecat society: They all know what you're thinking anyways. It's a mild example because, while that's a rule in Treecat society, they understand that such a mindset is not shared by most Humans and behave themselves while amongst them.
- Lest everyone forget...look no further than Journey to the West - this is very essence of the dynamic between Xuanzang and Sun Wukong.
- A Song of Ice and Fire:
- The Stark children's direwolves have grown up into extremely dangerous animals. The wolves have also saved their owners' lives on several occasions.
- Daenarys Targaryen's adorable little baby dragons grow up into, well, dragons. Take all of the problems associated with the direwolves and add a few tons of muscle, wings, the ability to breathe fire, and a voracious appetite.
- Alexa from The Last Dragon Chronicles. One could make the point that she's the mastermind behind it all...
- Journey to Chaos: The adult in this case and the leash is on Blood Drinker. The only thing stopping this Evil Weapon from eating everyone in sight is Basilard's will.
- Game of Thrones: Essentially how Tywin views Tyrion's relationship with the wildling clans.
- Mike holds the leash of Vyvyan on The Young Ones.
- At one point in The Girl from Tomorrow, one of the protagonists has the Big Bad under control with a device that controls his every movement. Eventually he's trusted enough to go places - heavily guarded and with the device at the ready - and saves a boy from drowning in order to convince his master that he's undergone a HeelFace Turn so he'll deactivate the device. It works, much to the distress of the title character, who doesn't buy it.
- In Scandal, Huck informs Olivia that, contrary to what she might think, he is very much a Retired Monster. Her taking him in gave her his Undying Loyalty but it did not change what he is. It's just that he has a leash now, which she holds.
Huck: You took in a wild monster, and you groomed me and petted me and trained me to sit at your feet. But that doesnt make me a puppy, Liv, that just makes me a very loyal monster. So I didn't go too far, I went exactly as far as my leash allows. And you hold the leash."
- In Person of Interest, the Machine becomes this to Root. To clarify: the all-seeing surveillance state AI is the benevolent leash-holder, and perky Amy Acker is the barely-restrained avatar of chaos and doom.
- On The Muppet Show and all movies featuring the Muppets, Floyd seems to be the only one who can keep Animal under any sort of control.
- An example of the rarer, more loyal variant: In the Dungeons & Dragons campaign setting Ravenloft, the class-based critters of wizards (familiars) and paladins (holy steeds) are transformed into entities known as "Dread Companions". These perverted versions of the ordinary companions are totally evil, but remain slavishly devoted to their master, to the point of acting on his or her subconscious desires.
- Zealotry abound in Tormenta. Servants of the goddess of Life revere fertility, healing, life and the product of those: Kids. The city of Smokestone is home to the Children, a group of clerics of Lena that pledged their loyalty to a group of kids that they raise. Even though they learn to never harm other people (it's part of Lena's restrictions), having kids leading over a bunch of adults with the power to channel the wrath of a god is an excellent way to show how evil those little bastards can get.
- Monsters and Other Childish Things is essentially Kid with the Leash : The RPG. The player characters are ordinary children whose best friends happen to be hideous, often-Lovecraftian monsters.
- Leviathan: The Tempest: Deconstructed with Atolls, who effectively have the ability to enthrall Leviathans much as Leviathans enthrall ordinary humans. A few words from an Atoll can permanently add dots to a Leviathan's Karma Meter or take them away. The book makes it very clear that these relationships tend to be incredibly dysfunctional on both sides.
- Final Fantasy: Summoners in general count as these are nasty creatures and the summoners are typically children to young adults.
- Final Fantasy IX: Eiko is the last of the summoners and is one of the two youngest in the group.
- Final Fantasy X: Yuna A 17 year old girl (so yes, she's still a 'kid' ) who can summon a large number of beasts to fight for her.
- Final Fantasy XII The summon creatures in this game are explictly evil and bound by magic seals to obey the heroes.
- In Star Wars: Knights of the Old Republic, the assassin droid HK-47 enthusiastically offers to kill almost every character you meet. (Whether or not you allow him to do so is up to you.)
- In Summon Night: Swordcraft Story 2, the player may choose the half-angel, half-devil Dinah as their Guardian Beast. Her devil half claims to be heartless and evil, and that she's forced by circumstance to work for the main character. Her catchphrase is "I guess I don't have a choice", whenever Edge/Air announces his/her plans to do anything. Her failure to be completely evil is just that blasted angel interfering plus enlightened self-interest, honest! No, really!
- Van Vat Tran and his minion Archibald Grimms in Super Robot Wars Original Generation 2, who keeps Archibald in line with careful instructions, insanity notwithstanding... mostly to keep him from slaughtering civilians. For a villain, Van isn't a bad guy.
- Felt holds the leash of the Azure Azoth in Atelier Iris 2: The Azoth of Destiny. The all-powerful sword (capable of destroying continents) insists on killing to get rid of obstacles and complains about Felt's moral choices.
- The premise of the game Okage: Shadow King is somewhat of an inversion of this, as the kid with the leash is actually subservient to the Omnicidal Mani... er... evil demon king. At least, in theory...
- Street Fighter III has Hugo, a brutal, beastly mountain of a man... who is kept in check by his manager, Poison.
- The protagonist of Soul Nomad & the World Eaters, who keeps Omnicidal Sociopathic Hero Gig on a very short leash by having imprisoned Gig's soul inside his/her own body and extracting minuscule amounts of godly power from Gig as a form of lease for having him stay there. Gig, on his side, finds the protagonist repellently noble and constantly tries to goad the protagonist into doing acts of evil or tempting him into accepting more of his powers, which will grant Gig more control over the protagonist's body.
- An interesting subversion can happen during a New Game+, where the protagonist has the option of becoming enamoured with his power and lets go of the leash, resulting in him becoming an Omnicidal Maniac who's as bad as, if not worse than, Gig himself. Who of course finds the whole thing hilarious and starts handing out power like it was Christmas time. Right up until he realizes that maybe supporting the crazy wasn't such a good idea when he gets eaten by the protagonist himself
- Several of the demons/personae in the various Shin Megami Tensei games border on this. You know, because so many of them are Olympus Mons.
- Subverted in several ways with Touhou and Remilia/Flandre. Fits because Flandre is Ax-Crazy insane and only Remilia (and to lesser extent Sakuya, her maid) keeps Flandre under control. Subverted because Flandre is actually younger than Remilia (not by much though), because they're both about 500 years old vampires, and because they're actually sisters.
- Wendy in Rule of Rose controls the serial killer Stray Dog by pretending to be his dead son, and literally walks him on a leash and trains him like a dog. Once she sets him loose, there's no stopping him, however.
- Beyond: Two Souls: The protagonist, Jodie, has spent her entire life with a Poltergeist-like entity called Aiden. Aiden seems to genuinely care for Jodie's wellbeing and does what it can to protect her, usually taking orders from her, but sometimes, Aiden acts on his own and can get quite malevolent if provoked. For this reason, hurting Jodie is generally a very, very bad idea.
- In Wayward Souls, this is the entire driving force behind the Cultist's storyline. Her cult runs on Powers via Possession, using tattoos and raw willpower to keep the demons from taking over completely. She enters the dungeons to test the capabilities of her new demon, who is still fighting hard for total control. She wins by threatening to repent (which, judging by the demon's Villainous Breakdown, would banish it) if it goes too far, though each still sees the other as a pet for the rest of the game.
- The Walrider of Outlast can only exist while bonded to a human host, and will obey that person's every whim with mindless determination. If said host wants someone dead, the Walrider makes sure they are very dead. By the end of the game, the protagonist is the Walrider's new host, and now has an extremely violent, extremely powerful entity under his control.
- In Gunnerkrigg Court, the fox spirit Reynardine possesses one of Antimony's old toys. Unfortunately for Rey, because she owns his current host, she also owns him; he more or less has to do as she says. The court isn't very happy about it, but confiscating Reynard wouldn't be a legitimate ownership transfer and could free him. As of Chapter 52, Antimony has given Reynard to Kat rather than give him to her father.
- The Order of the Stick, where Roy (Lawful Good fighter and party leader) is one of the few things keeping Belkar (Chaotic Evil halfling ranger and barbarian) in check. Occasionally with a magical Restraining Bolt, but not as the main tool.
- The cast of Sluggy Freelance try to do this with Bun-Bun. They don't have much in the way of actual control over him, but they've gotten rather good at arranging situations so it's in Bun-Bun's best interest to help them. Or at least in his best interest not to skin them alive.
- Goblins has an inversion in Kin, a kind and heroic yuan-ti (snake-person), kept on a literal magical leash by the significantly less benevolent Captain Goblinslayer.
- The undead warlock Richard from Looking for Group is an Omnicidal Maniac held back (sometimes) by group leader Cale. Though as Richard is, by far, the strongest member of the group, Cale has had to be a bit more tolerant than Roy.
- Girl Genius: The Heterodyne family serves as a family of psychopathic mad scientists with the leash to Castle Heterodyne.
- Agatha is one of the few with any empathy, kindness, or respect for other humans. However, Agatha has to watch how she orders the Castle. It tends to interpret her orders... creatively.
- Agatha's father and uncle were the "Heterodyne Boys", heroic adventurer sparks who tried to help other people as well. This trope applies in several more cases, too; the Heterodynes had lots of servants to the line, including the Castle itself, the Jagers, and the people of Mechanicsburg. Agatha, through her mother's Compelling Voice, also has some degree of control over several of the geisterdamen, the slaver wasps and creatures, and anyone infected with the new slaver wasps.
- In Manly Guys Doing Manly Things Jared the ex-Pokémon trainer has a Gyarados which he named Mr. Fish as his partner. He was kicked out of the Pokémon League because he wasn't tight enough with the leash and allowed Mr. Fish to eat his competitors. Aside from this Mr. Fish is completely loyal to Jared.
- Lydia is this quite literally for Betelgeuse in the first several chapters of Cobweb and Stripes. He invokes an ancient magical law which changes his punishment from straight-up imprisonment to being bound to a mortal anchor, and invisible chains prevent him from moving far from her side.
- In Worm, Tattletale figures out how to direct the Endbringers.
- Though not exactly a kid, the SCP Foundation has SCP-1055, a biomass that resembles a teddy bear under normal conditions and will spontaneously and unceasingly grow in size in relation to the number, proximity, and emotional state of people who are aware of it. The only known method of containment involves Mikey, a man with autistic spectrum disorder and Down's syndrome: his condition means he does not properly register as aware of SCP-1055 and he feels genuinely protective of it, thus not triggering its growth.
- Lydia Deetz from the cartoon version of Beetlejuice is the only character who can keep the eponymous Anti-Hero under control. She's a blend of this trope and Morality Chain; he genuinely adores her and will (however reluctantly) behave himself if she asks.
- In The Grim Adventures of Billy & Mandy, the Grim Reaper is forced to become the best friend of Mandy (a sociopathic Creepy Child) and Billy (who's dumber than pond scum).
- Mina and The Count: Vampire mellows out for a little girl.
- Jackie Chan Adventures: Jade once got control of the Shadow Khan. It was...interesting, to say the least; they were perfectly loyal to her, but maintaining control of them turned Jade evil.
